cheek weld is more of a chin weld. I have a 20 moa rail, medium rings, and a Leupold MK IV 6.5x20 scope. I might be able to fit low rings but that will only lower the scope .10 inch. I have looked around and like an adjustable stock. Do we still have a forum member that is modifying these stocks and would it hold up to 300 win mag ? My gun came with the H.S. precision. Thanks.
